Apple has unveiled its new iPhone line-up with three new handsets, including the £1,000 iPhone X.

The new iPhone 8 and 8 Plus both feature wireless charging, as well as improved cameras and processors, while the X – pronounced as ‘ten’ - is Apple’s first edge-to-edge screen and has facial recognition.

Here are the key features of Apple's new smartphones.

The two phones are both dust and water resistant, and feature 12-megapixel rear cameras.

The 8 has a 4.7-inch screen and the 8 Plus a 5.5-inch display.

The 8 Plus has dual cameras, and has new technology called Portrait Lighting to improve lighting on faces

Elsewhere, the 8 and 8 Plus also house the new A11 bionic chip, which Apple says improves processing time and efficiency on the device.

The iPhone 8 will start at £699, and the 8 Plus £799. Both devices go on sale on September 22.

iPhone X

The special edition version of the iPhone, the X is a complete re-design of Apple's phone.

It has Apple’s first edge-to-edge display and is the first iPhone to use an OLED screen and the first Super Retina display.

The 5.8-inch screen fills most of the front panel, and there is now home button. Instead users can swipe upwards to unlock the device and leave apps.

The ID fingerprint scanner in the home button has been replaced by facial recognition technology that scans a user's face to unlock the device and which works in daylight and at night Apple says

The technology is also at work in Animoji, new animated emoji that users can animate using their own face, changing the expressions of the characters on screen, and sending them in messages

Dual real cameras on the X - both 12-megapixel also both feature optical image stabilisation for the first time.

It will be available in two colours - space grey and silver - when it goes on sale on November 3, with prices starting at £999, the highest ever for an iPhone.

Expect BIG sales despite the price tag

Apple's new iPhone X is the "future of smartphone design" and will still be a success despite its near £1,000 price tag, one analyst believes.

Apple used a live event on Tuesday to unveil the special edition iPhone to mark its 10th anniversary, complete with an edge-to-edge screen and facial recognition technology.

Would you pay £999 for an iPhone X

The phone's starting price of £999 - which can rise to £1,149 for the highest specification version - was met with a mixed reaction on social media.

The device goes on sale on November 3, some two months after the iPhone 8 and 8 Plus, which begin shipping on September 22.

He said: "It will still sell in enormous volumes because Apple has repeatedly demonstrated its ability to persuade consumers to shift their overall spending to place a greater share of their disposable income towards a smartphone purchase.

"And the starting price of 999 dollars (in the UK it will be £999) is only 33 dollars more than the previously most expensive iPhone, the 7 Plus 256GB."

The iPhone X was the showpiece announcement at Apple's first event to take place on its new Apple Park campus - inside the new Steve Jobs Theatre.

Chief executive Tim Cook paid tribute to the late co-founder at the beginning of his keynote, calling the venue a tribute to "Jobs and his vision".

A third-generation Apple Watch, which contains its own mobile signal and can be used to make phone calls independent of a smartphone, was also announced alongside the Apple TV 4K.
